Acceleration is in the cards. But think about it. 3mm/year=30 cm/century will, after all, cost us 30 meters of land all along the coast, assuming a 1 percent grade. More, if the grade is shallower, as it often is in the most valuable river delta croplands. And that cost will be doubled the next century, and the next.

That’s actually a fair amount of land. Don’t blow it off as trivial. Or “kind of silly”. But this greatly underestimates the problem. The Greenland ice cap is going to melt. At any rate, a lot of it is. Now we’re talking several meters sea rise. That means scores of miles, or worse.

Beyond just satellite measurements, we also have rough ground measurements of sea level changes going back decades. There has not been an acceleration. Further, the current changes in sea level are not out of the ordinary. In terms of natural changes, sea levels have increased dramatically since the last ice age and will continue to increase (slowly) until our next one.

As far as your second paragraph, a time frame is needed. I would suggest this study to you: colorado.edu which explains that incredibly high predictions for sea level changes are physically imposssibl.
